Matthew 10:28
Amplified Bible (AMP)
28 And do not be afraid of those who kill the body but cannot kill the soul; but rather be afraid of Him who can destroy both soul and body in hell (Gehenna).
I always thought of this Bible text and wonder if literally at death our soul continues to exist in a state of inanimation or asleep , and only God is who deside which of them will be destroyed. Another thing I think is why Jesus himself said:
Luke 23:46 New International Version (NIV)
46 Jesus called out with a loud voice, “Father, into your hands I commit my spirit.” [a] When he had said this, he breathed his last.
